2m aprs antenna

Im looking for an small antenna (unity gain?) for aprs use only. Im open for any suggestions, glass, nmo, mag, any mount out there. But dont want another long antenna hanging off the car. Its starting to look like a porcupine already.

Any old 1/4 wave will do. You'll want good seperation from your other antenna if you generally operate on two meters. Even then it is hard to keep one from desensing the other. That is why I switched to the Kenwood TM-D700 - no more interfering with myself.

Larsen make a nice short dual band antenna. I don't recall the model number though. It's well built and spring loaded. I bought one a few years back for garage clearance. I use it probably about 90% of the time. I only switch to a higher gain antenna for road trips.

You may want to consider selling the rigs you have and looking for a Kenwood TMD700 or D710. That way, you will only need one antenna for APRS, and the muting of the second receiver is handled for you in advance.

To some extent, your antenna will affect your performance. If you're close to an iGate most of the time, it probably isn't critical at all. If you're operating on the fringes, you may want something bigger.
